Ford F-250 7.3 Gas Engine Axle Ratios
Is there much difference in towing milage, and around town/highway mileage with the new F-250 7.3 gas engine with rear gear options? Considering 3.55 or 4.30 axles ratios. Any input is helpful.

I’d say why would one spend $50-60k on a tow rig with the biggest engine and NOT get the best performance out of it with deep gears.
Not like it’s winding up at highway speeds with the 10 speed.
That’s like ordering a pepperoni pizza because you like pepperoni and opting for less pepperoni...
Fuel mileage is also part of the best performance factor. With a taller ratio, the transmission is less busy, especially with a ten speed. And there’s no logic in making the 1st two gears virtually useless unless you’re going to be rock crawling. Makes more sense to have lower rpm at the top when not towing.
Less pepperoni is healthier.
